Reaction Steps
2-(4-Methylphenyl)ethyl alcohol (VIII) (2.72 g, 0.02 mole), 4-nitrochlorobenzene (IX: X=Cl) (3.15 g, 0.02 mole) and potassium hydroxide (1.4 g, 0.025 mole) were added to benzene (60 ml), and dicyclohexyl-18-crown-6 (0.2 g) was added thereto, followed by reaction at 60° C. for 10 hours. The reaction mixture was washed with water and concentrated, and the precipitated crystals were recrystallized from 95% ethanol to obtain 4.5 g of 4-[2-(4-methylphenyl)ethoxy]-nitrobenzene (VI) as white crystals (yield, 87.5%).
